The invention is based on an electric device, in particular an electric hand tool, having a removable power supply unit (), an accommodation region () for accommodating the power supply unit (), and a locking device () for locking the power supply unit () to the accommodation region (). It is proposed that the locking device () is provided for the purpose of unlocking the power supply unit () from a locked state&#x2014;by means of a force which is exerted on the power supply unit () and moves the entire power supply unit () in relation to the accommodation region ().

Electrical device, in particular an electrical hand-held power tool

A handle for an electric hand tool, which in use, is detachably connected to the hand tool as an auxiliary handle (), includes at least one detection device (), which communicates with at least one regulating and/or control element in the electric hand tool through a contactless signal transmission device.

Handle with detecting unit

The present invention relates to a method for graphically displaying a sectional image of an object under examination () having objects () situated therein, in particular for the display of a sectional image of a building wall. The invention provides that the sectional image with the objects () situated in the object under examination () is displayed already while data acquisition by the position detector () is taking place.

Locating device and corresponding method

A marking device, in particular a hand-held marking tool for positioning markings, comprises first means () which make it possible to position the device () in a predefinable first position of a reference surface (), and second means () for leveling the device () relative to the reference surface (), as well as a tracking system () for determining a distance covered by the device () relative to the first position of the device. The tracking system () detects the movement of the measuring instrument () on the reference surface () in two orthogonal directions ().

Marking device

A handheld device. In particular a locating device, includes a housing (), which is movable with a handle unit () over a surface of an item being examined and which has a sensor unit () for picking up a first motion parameter. At least one second motion parameter can be detected with the sensor unit ().

Handheld locating device with a sensor for detecting motion parameters

A quick-action chuck, in particular for a power tool, has an actuating element () and a control device which includes at least one mechanism () for controlling at least one locking device () that serves to absorb a chucking reinforcement force via the locking device () that is controllable by the control device, a positive-engagement connection can be brought about for absorbing the chucking reinforcement force.

Quick-action chuck

A quick chuck for a hand power tool has an actuating element, at least one arresting element for receiving a clamping support force, a control device having at least one control unit for controlling the at least one arresting element, the arresting element controllable by the control device producing a form-locking connection for receiving the clamping support force.

Quick chuck

An electric hand tool having a machine housing, with an electric motor accommodated in the machine housing for driving a tool, and a fan wheel accommodated in the machine housing for generating a main cooling air current that flows from a main air inlet to a main air outlet through the machine housing, which said fan wheel creates a suction space and a pressure space on opposite sides when it rotates, wherein means for generating an additional air current are provided and configured such that the additional air current flows onto at least one machine component that is located outside of or in a low-flow region of the main cooling air current, wherein the electric motor includes a motor winding with winding heads that project outward on at least one end face of the electric motor, the fan wheel is located with axial clearance in front of the end face of the electric motor and is configured such that the suction space is located in front of the end face of the electric motor where the winding heads are located, and the means for generating the additional air current have additional air inlets that lead into the suction space, wherein the additional air inlets are passages located in a dividing wall that separates the pressure space from the suction space and, preferably, the passages are separated from the axis of the fan wheel by the greatest radial distance possible.

Electric hand tool

A power tool with a housing () and a tool () located thereon such that it is capable of being driven in a rotating and/or oscillating manner, the tool being operable as directed using vacuum flow, in particular using a vacuum cleaner. The power tool is made particularly powerful by the fact that a radial turbine wheel () with forward-guiding and rearward-guiding vane rows () functions as the drive.

Power tool

The invention is based on a device () with a sensor, which is guided with one hand () over a surface () and in which the data detected are displayed by a display unit (). The invention proposes that grasping surfaces () for the hand () be positioned on two approximately diametrically opposed sides of a grip (), at least one of which sides has a sensor () that detects the number of fingers () resting against this grasping surface ().

Device equipped with a sensor

A positioning device includes a housing () and a display unit (), in particular a display for graphic representation of measurement information, which display is movable for locating purposes using a handle unit () over a surface of an article being examined. The device has at least one sensor unit () for picking up a first motion parameter. At least one motion measuring direction () extends transversely to the longitudinal direction () of the housing ().

Locating device

In order to disclose a structure, which performs the functions of a structured, organic, electrically conductive, transparent electrode and an orientation layer, a cost-reducing and time-saving method for producing such a structure, and uses of this structure, the invention proposes a layer on a substrate, which layer contains an organic, transparent, electrically conductive material and which has a preferred orientation, a method for producing such a layer, in which a transparent, electrically conductive layer is produced and oriented on a substrate, and a use of such a layer as a combined electrode-and orientation layer in LC displays.
